GEORGE B. FOWLER, OF BROOKLYN, ASSIGNOR OF ONE-HALF TO ANDREW PECK AND WASHINGTON I. SNYDER, BOTH OF NEW YORK, N. Y.

HAND-GRIP TESTER.

srncrrrcn'rrolv forming part of Letters Patent No. 344,095, dated .Tune 22, 188e.

Application filed March 6, 1886.

arm hinged thereto and having an interposed spring, and a rod connecting said arm with a pointer on a scale or registering plate, to register the amount of pressure applied to the arm.

In the accompanying drawings, which fully illustrate my invention, Figure 1 is a side elevation of myimproved hand-testing machine; and Fig. 2 is an enlarged detail view in per- 2o spective, showing the link-connection between the griparm and the indicator.

Let a represent an upright bar or post mounted on the tlat base-piece b. On the lower end of the post is a collar, c, having side flanges or lugs, d d, to which an upright arm, e, is pivoted by means of the pinf. This arm bends outward to about midway of its length, and on its outer surface are formed a number of depressions, g, adapted to receive 3o the fingers when the instrument is grasped with the hand.

h is a spiral spring interposed between the post and its movable arm, the endsof the spring being loosely held in recesses formed in the post and arm.

To the upright bar or post c, near its top, is secured a horizontal bar, i, which serves as a guidebar, on which the arm e moves. A projection, Z, on the top of the arm e is pro- 4o vided with a slot, k, to receive the bar t', and

pins 0r studs Z prevent the arm e from slipping off of the guidebar by the action of the spring. A projecting plate, m, on the top of the movable arm e forms a bearing for the fingers, to prevent their slipping when the instrument is gripped.

To the upper part of the post a is secured the curved scale n, graduated to indicate pounds pressure, and having the hand or pointer o. The end of the pointer is connected with the movable arm e by the rod p, which Serial No. 194,280. (No model.)

passes through and works in the vertical piece j, projecting from the top of the movable arm e. A head on the end of the rod p holds it in position.

In operation the instrument is embraced by the hand, the ngers resting in the depressions. The amount ofgrippingpower exerted on the arm e to move it is registered by the pointer on the scale.

The upper portion of t-he post c is made detachable and in the form of a hollow case, a, suitable to contain a device, w', consisting of a stem carrying a cutting-blade and operated by a spring for clipping oft' the ends of cigars. 65 A hole, w, in the side of the case is provided for the insertion ofthe end of the cigar. The ends of the upper section and of the main post are provided with screw-threads and screw one upon the other.

WVhat I claim as new, and desire to secure by Letters Patent, is-

1. A handgrip tester comprising a standard having an arm hinged thereto, a spring arranged to bear against said arm, a scale, and a pointer connected to the movable arm, for registering the amount of pressure applied, as set forth.

2. In a hand-grip tester, thecombination of the register n, pointero, standard c, arm e, 8o hinged thereto, rod p, and spring h, all arranged and operating as set forth.

3. The combination of the standard @,hinged arm c, spring h, slotted plate l, bar t', rod p, pointer o, connected to arm e, and scale n, as set forth. v

4. In a hand-grip tester, the combination of the post a, having the iiat base b and provided with a detachable top part containing a cigar-clipping device, hinged arm e, pointer 9o o, connecting-rod p, scale n, and spring h between the iiXed post and movable arm, as set forth.

5. The combination, with the post a, scale n, pointer 0, and connecting rod h, of the hinged arm e, provided with nager-recesses g and bearing-plate m, as and for the purpose set forth.
